Band 6 drives tool apron 5 to do radial feed movement.
Transmission belt 6 uses flexible steel band, and both ends are fixed on 5 both ends of tool apron, the transmission belt 6 of the utility model can there are two types of
Embodiment, the first is using a whole flexible steel band, and 6 both ends fixed position of transmission belt does adjustable mode, for example uses spiral shell
Silk lock transmission belt 6, transmission belt 6 needs draw tighter, just screw twist it is deeper, other modes can also be used adjust tensioning,
With regard to different one for example, the unused Detailed description of the invention of the embodiment.The another embodiment of transmission belt 6 is as shown in Fig. 3, transmission
Band 6 links together for more piece, likewise, 6 both ends of transmission belt are fixed on tool apron 5, the non-adjustable tensioning of fixed position connects phase
Regulating mechanism 14 is arranged in the connecting portion of adjacent two section transmission belts, and regulating mechanism 14 in the present embodiment is exactly that transmission belt 6 connects
It is double threaded screw that setting adjusting nut 142 in end, which is contrary adjusting screw rod 141(by both ends) it is connected and fixed, it adjusts
Double threaded screw is rotated when rate of tension.The utility model is driven using transmission belt 6, can be solved existing mechanically operated
Drawback, such as, cutterhead 1 is disk, and when rotation can generate centrifugal force, and the center of gravity of tool apron 5 whole (adding lathe tool) is crossing cunning
When the central point in dynamic rail road, the direction of centrifugal force is different, if machine driving, such as rack-and-pinion, contract block etc., all can
There is gap, will appear following situation, such as feed process in whole cross when central point generates phase counter centrifugel of tool apron 5,
A distance has been fed, central point is at this time crossed, cutting point will dash forward or shrink back because of centrifugal force, it is difficult to control
Mismachining tolerance processed, and transmission belt 6 uses flexible steel band, there is no gaps or double threaded screw to connect for a complete transmission belt
Position tightening force always on the contrary, gap will not be generated, it is ensured that machining accuracy, not by centrifugal forces affect.
